NEW OPi NOTEWORTHY SPECIES. 108 



broadly rhombic-lanceolate, serrate or laciiiiate-cleft and 2 to 

 10 incbes long, supported on a stout fistulous petiole ; the 

 later radical 3-lobed or -divided and passing to the truly 

 pinnate, which have but 2 pairs of broadly lanceolate acute 

 serrate leaflets : the bracts of the involucre broadly lanceolate, 

 tapering at both ends : fruit 1^ lines long, strongly ribbed. 



Brackish marshes near Suisun, California, where it is 

 associated with Cicida Bolanderi. It is always aquatic, and 

 as compared with S. cicidcefoliam in which the lowest leaves 

 are the most dissected, reverses the order of leaf development. 

 Except at high tide the simple blade of these lowest leaves is 

 always emersed; but is borne on a stout hollow jointed and 

 more or less submersed petiole. 



Mentzelia affinis. a stoutish annual, often 2 feet high, 

 with white and shining glabrous stems, simple and leafy 



below, widely branching above : leaves lanceolate, deeply 

 sinuate -pinnatifid : flowers scattered, ^ inch broad, yellow : 

 calyx-lobes attenuate-subulate, J inch long : capsule 1 inch 

 long, almost linear, hispid witli short stiff hairs which are 

 strongly pustulate at base : seeds short-cubical, the angles 

 grooved, the surface muriculate. 



California, from the plains of the San Joaquin near Lathrop, 

 southward to the foot-hills of San Bernardino County, where 

 it has been collected and distributed by Mr. Parish as "J/. 

 dispersa"': also at San Jacinto, San Diego County, Mrs. L. 

 Gregory. A much larger plant than either of its allies J/, 

 albkauUs and dispcrsa, having the foliage of the former, and 

 necessarily separated from the latter by its long aristiforra 

 calyx-lobes and shorter seeds. 



Brickellia rhomboidea. Shrubby tliroughout and irregu- 

 Ifiily branching, 3 to 5 foot high : leaves thin, rhomboid or 

 (deltoid, coarsely toothed or subentire : inflorescence scattered 

 and cymose at" the ends of the divergent and leafy branches, 

 hispidulous-pubescent, but not in the least glandular : invo- 

 lucre 4 lines long : achones puberulent.
